NAME
       mysqladmin - client for administering a MySQL server

SYNOPSIS
       mysqladmin [options] command [command-options] [command
										      [command-options]]
										      ...

DESCRIPTION
       mysqladmin is a client for performing administrative operations. You
       can use it to check the servers configuration and current status, to
       create and drop databases, and more.

       Invoke mysqladmin like this:

	  shell> mysqladmin [options] command [command-arg] [command [command-arg]] ...

       mysqladmin supports the commands described in the following list. Some
       of the commands take an argument following the command name.

	 create db_name

	  Create a new database named db_name.

	 debug

	  Tell the server to write debug information to the error log.

	 drop db_name

	  Delete the database named db_name and all its tables.

	 extended-status

	  Display the server status variables and their values.

	 flush-hosts

	  Flush all information in the host cache.

	 flush-logs

	  Flush all logs.

	 flush-privileges

	  Reload the grant tables (same as reload).

	 flush-status

	  Clear status variables.

	 flush-tables

	  Flush all tables.

	 flush-threads

	  Flush the thread cache.

	 kill id,id,...

	  Kill server threads. If multiple thread ID values are given, there
	  must be no spaces in the list.

	 old-password new-password

	  This is like the password command but stores the password using the
	  old (pre-4.1) password-hashing format. (See Section 6.9, Password
	  Hashing as of MySQL 4.1.)

	 password new-password

	  Set a new password. This changes the password to new-password for
	  the account that you use with mysqladmin for connecting to the
	  server. Thus, the next time you invoke mysqladmin (or any other
	  client program) using the same account, you will need to specify the
	  new password.

	  If the new-password value contains spaces or other characters that
	  are special to your command interpreter, you need to enclose it
	  within quotes. On Windows, be sure to use double quotes rather than
	  single quotes; single quotes are not stripped from the password, but
	  rather are interpreted as part of the password. For example:

	  shell> mysqladmin password "my new password"

	 ping

	  Check whether the server is alive. The return status from mysqladmin
	  is 0 if the server is running, 1 if it is not. This is 0 even in
	  case of an error such as Access denied, because this means that the
	  server is running but refused the connection, which is different
	  from the server not running.

	 processlist

	  Show a list of active server threads. This is like the output of the
	  SHOW PROCESSLIST statement. If the --verbose option is given, the
	  output is like that of SHOW FULL PROCESSLIST. (See Section 5.4.20,
	  SHOW PROCESSLIST Syntax.)

	 reload

	  Reload the grant tables.

	 refresh

	  Flush all tables and close and open log files.

	 shutdown

	  Stop the server.

	 start-slave

	  Start replication on a slave server.

	 status

	  Display a short server status message.

	 stop-slave

	  Stop replication on a slave server.

	 variables

	  Display the server system variables and their values.

	 version

	  Display version information from the server.


       All commands can be shortened to any unique prefix. For example:

	  shell> mysqladmin proc stat
	  +----+-------+-----------+----+---------+------+-------+------------------+
	  | Id | User  | Host	   | db | Command | Time | State | Info 	    |
	  +----+-------+-----------+----+---------+------+-------+------------------+
	  | 51 | monty | localhost |	| Query   | 0	 |	 | show processlist |
	  +----+-------+-----------+----+---------+------+-------+------------------+
	  Uptime: 1473624  Threads: 1  Questions: 39487
	  Slow queries: 0  Opens: 541  Flush tables: 1
	  Open tables: 19  Queries per second avg: 0.0268

       The mysqladmin status command result displays the following values:

	 Uptime

	  The number of seconds the MySQL server has been running.

	 Threads

	  The number of active threads (clients).

	 Questions

	  The number of questions (queries) from clients since the server was
	  started.

	 Slow queries

	  The number of queries that have taken more than long_query_time
	  seconds. See Section 10.4, The Slow Query Log.

	 Opens

	  The number of tables the server has opened.

	 Flush tables

	  The number of flush-*, refresh, and reload commands the server has
	  executed.

	 Open tables

	  The number of tables that currently are open.

	 Memory in use

	  The amount of memory allocated directly by mysqld. This value is
	  displayed only when MySQL has been compiled with --with-debug=full.

	 Maximum memory used

	  The maximum amount of memory allocated directly by mysqld. This
	  value is displayed only when MySQL has been compiled with
	  --with-debug=full.


       If you execute mysqladmin shutdown when connecting to a local server
       using a Unix socket file, mysqladmin waits until the servers process
       ID file has been removed, to ensure that the server has stopped
       properly.

       mysqladmin supports the following options:

	 --help, -?

	  Display a help message and exit.

	 --character-sets-dir=path

	  The directory where character sets are installed. See Section 9.1,
	  The Character Set Used for Data and Sorting.

	 --compress, -C

	  Compress all information sent between the client and the server if
	  both support compression.

	 --count=N, -c N

	  The number of iterations to make for repeated command execution.
	  This works only with the --sleep option.

	 --debug[=debug_options], -# [debug_options]

	  Write a debugging log. The debug_options string often is
	  d:t:o,file_name. The default is d:t:o,/tmp/mysqladmin.trace.

	 --default-character-set=charset_name

	  Use charset_name as the default character set. See Section 9.1, The
	  Character Set Used for Data and Sorting.

	 --force, -f

	  Do not ask for confirmation for the drop db_name command. With
	  multiple commands, continue even if an error occurs.

	 --host=host_name, -h host_name

	  Connect to the MySQL server on the given host.

	 --password[=password (INSECURE)], -p[password (INSECURE)]

	  The password to use when connecting to the server. If you use the
	  short option form (-p), you cannot have a space between the option
	  and the password. If you omit the password value following the
	  --password or -p option on the command line, you are prompted for
	  one.

	  Specifying a password on the command line should be considered
	  insecure. See Section 7.6, Keeping Your Password Secure.

	 --port=port_num, -P port_num

	  The TCP/IP port number to use for the connection.

	 --protocol={TCP|SOCKET|PIPE|MEMORY}

	  The connection protocol to use.

	 --relative, -r

	  Show the difference between the current and previous values when
	  used with the --sleep option. Currently, this option works only with
	  the extended-status command.

	 --silent, -s

	  Exit silently if a connection to the server cannot be established.

	 --sleep=delay, -i delay

	  Execute commands repeatedly, sleeping for delay seconds in between.
	  The --count option determines the number of iterations.

	 --socket=path, -S path

	  For connections to localhost, the Unix socket file to use, or, on
	  Windows, the name of the named pipe to use.

	 --ssl*

	  Options that begin with --ssl specify whether to connect to the
	  server via SSL and indicate where to find SSL keys and certificates.
	  See Section 7.7.3, SSL Command Options.

	 --user=user_name, -u user_name

	  The MySQL username to use when connecting to the server.

	 --verbose, -v

	  Verbose mode. Print more information about what the program does.

	 --version, -V

	  Display version information and exit.

	 --vertical, -E

	  Print output vertically. This is similar to --relative, but prints
	  output vertically.

	 --wait[=count], -w[count]

	  If the connection cannot be established, wait and retry instead of
	  aborting. If a count value is given, it indicates the number of
	  times to retry. The default is one time.


       You can also set the following variables by using --var_name=value
       syntax:

	 connect_timeout

	  The maximum number of seconds before connection timeout. The default
	  value is 43200 (12 hours).

	 shutdown_timeout

	  The maximum number of seconds to wait for server shutdown. The
	  default value is 3600 (1 hour).


       It is also possible to set variables by using
       --set-variable=var_name=value or -O var_name=value syntax.  This syntax
       is deprecated.
